A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the extended area of Kikinda. The impact of the industrial water sources on the regime of the public water supply source will also be assessed. The radius of influence of the groundwater source is determined by simulating the travel of conservative particles over a period of 200 days.
